Arequipa, Peru, February 20th, 2013 — Gold Horizons Mining Co. Ltd. continues to focus on mine development in anticipation of their new Yuromayo Processing Plant scheduled to begin operating in Q1 of 2013. Exploration and development of the 40 meter Blanca mining shaft has been underway since the beginning of 2013. This work has included the widening, reinforcing and general improvement of the vertical direction of the shaft to allow for the installation of electric winches and a highly efficient ventilation system. At a depth of 20 meters two fronts have been started and several meters of new tunnels developed producing several hundred tons of fresh mineral. Mineral samples were collected and the lab results reported on 5/2/2013 show 22.33 grams per ton. Previous assays came in at 13 and 24 grams per ton. These results are significantly better than management’s forecast and the Company is really overjoyed to see such a result confirmed. While these samples do not constitute the entire vein nor do they assure us an average grade per ton we do believe consistent high levels of gold concentration represents a positive perspective on the overall resource value and profitability of the mine.
